SpotColor to GrayColor converter (javaScript)

-

this edited change spot color grayscale, aimed @ color called "spot black". reason better using "edit/edit colors/convert grayscale" tones stay same value. i'm sure improved, i'm sharing if having issues having might have easier time fixing it. script originated carloscanto on discussion http://forums.adobe.com/thread/1267562?tstart=0 , discussed further in discussion http://forums.adobe.com/message/5610447#5610447. enjoy.

a file shows script hosted here https://docs.google.com/file/d/0bzeojsydhh_weknoytfzvhvaoxm/edit?usp=sharing until forget why it's saved there , delete it.

nice work on progress/additions have made through these threads, stuff, thanks sharing , carloscanto well.
